  • Patent number: 4540616
    Abstract: A carcass shroud is formed from a liquid water porous hydrophobic and oleophilic polyolefin sheet. Preferably, the sheet is a spun-bonded fabric, such as spun-bonded polypropylene or a perforated polyolefin film having liquid water porosity. Preferably, a surfactant is dispersed throughout the shroud fabric or coated onto the film. Sodium chloride may also be dispersed in the shroud or onto the shroud surface. Such a carcass shroud can be applied to a carcass in a dry state, i.e., without being wetted with brine prior to application. The porous nature of the sheet or film allows liquid water to pass through while the oleophilic nature of the material causes it to hug tightly to the warm fat of the carcass. The salt acts to bleach the surface of the carcass and the surfactant acts to draw blood from the carcass, substantially enhancing its appearance. After cooling, the shroud readily releases from the carcass and does not leave fibrous contamination, as do known shrouds.

  • Patent number: 4223043
    Abstract: A flexible tube container has a plurality of cells linearly disposed along the length of the tube. The cells are defined by a plurality of segmented weld lines, each segmented weld line extending the width of the tube. Each segmented weld line permits fluid communication between the various cells in the container and the formation of individual frozen confections within each of the cells upon freezing of the fluid therein. Dispensing of an individual frozen confection is easily done by bending the tube along any segmented weld line, which detaches an adjacent cell containing an individual frozen confection and immediately permits sanitary consumption of the frozen confection while it is hygienically protected within the detached cell.

  • Patent number: 4196220
    Abstract: A tubular food casing is treated with an admixture of an albumin and a modified liquid smoke to provide a casing that is suitable for imparting smoke flavor and intensified smear resistant smoke color to food products processed therein. Alternatively, a casing is treated first with an albumin and then with a modified liquid smoke.This invention relates to methods of treating a food casing and also relates to the resultant improved treated casing, which is suitable to impart smoke flavor and intensified smear resistant smoke color to food products processed therein.In particular this invention relates to a method of coating a fibrous or non-fibrous regenerated cellulose tubular food casing and the resultant casing, which method encompasses coating the internal surface of the casing with an admixture of an albumin such as egg albumin, and a modified liquid smoke, to provide a casing which is suitable to impart smoke flavor and intensified smear resistant smoke color to food products processed therein.

  • Patent number: 4183964
    Abstract: Sausages are made by stuffing a meat emulsion into a thermosealable tubular casing, effecting preliminary sealing of the casing into "sausage lengths", at least partially cooking the product and then effecting a final sealing at the site of the preliminary seals which seals are wider than the preliminary seals and thereby compress the meat into the unsealed portion of the tube.

  • Patent number: 4164588
    Abstract: A package liner adapted to protect fragile articles during shipment, handling and display in retail establishments. The liner is made of an elongated, flexible packaging material, such as a single face corrugated paper pad, having a pair of spaced, oppositely disposed, outwardly bowed lines of weakness impressed across its central width. When the ends of the liner are folded upwardly and flexed into a generally tubular conformation, the area between the lines of weakness assumes a downwardly concave shape. The resulting U-shaped structure is adapted to receive the article therewithin and cushion it against breakage when the package is dropped or exposed to lateral shock forces.

  • Patent number: 4163463
    Abstract: This invention relates to an artificial sausage casing and a process for making the casing. In making a regenerated cellulose casing an oxazoline wax is incorporated into viscose in a proportion from about 1-20% by weight of the cellulose content in the viscose, the oxazoline impregnated viscose extruded into a tubular casing, coagulated, and the cellulose regenerated. The casing has excellent handle, flexibility, and peelability from sausages processed therein.
